PA Mining History
Room-and-pillar with retreat mining is a high-extraction mining method, generally recovering greater than 70% of the target coal seam. ANTHRACITE COAL. Anthracite coal is often described in layman's terms as 'hard coal' and while it is heavily metamorphosed and almost pure carbon, it is no harder or softer than bituminous, or 'soft' coal.
What is Surface Mining? (with pictures)
· This type of surface mining, also known as hard rock mining, is typically employed to extract metal ores, like copper, gold, iron, and aluminum, and other minerals. Strip mining is a form of surface mining that is primarily used for coal excavation. The rock and dirt covering the ore is removed one strip at a time.
